I did a motor swap from a totaled 15 pro into a 2012 that had a blown motor. I switched the ecu and the entire wiring harness as well as the voltage regulator and gauge. The only thing I didn't swap was the coils because they look identical and have the same plugs. Now I'm having issues with it not running to good and Iooked up the part numbers and noticed they are different numbers. Does anyone know if they are actually different? The engine ran great in the 15 before we took it out.
